About Schottky defect
Schottky defect
1- It is found in case of ionic crystals.
2- The electrical conductivity of the crystal increases.
3- The stability of the crystal decrease.
4- Equal number of cation and anions are missing from their normal lattice sites.
5- It decrease the density of the crystal.
6- Dielectric constant value remain same.
7- It is observed in case of ionic compounds having high co-ordination number.
8- these are noticed in case of ionic compounds where cation and anions are almost of equal sizes.
9- These are observed in case of alkali metal halides.
